Is little manganese in water good for health?

GOANEWS DESK, PANAJI | 01 April 2013 22:23 IST

“Having little manganese in drinking water is good for health”.

This is the way, may be in a lighter vein, PWD minister Sudin Dhawalikar today tackled the issue of increasing manganese content in Selaulim drinking water.

The issue was raised through a calling attention motion by Fatorda MLA Vijay Sardesai today as water supply was stopped for two days to Salcete and Mormugao talukas last week.

Dhawalikar admitted that manganese level in Selaulim dam has touched 1.2 mg/litre against the permissible limit of 0.7 mg/litre. 

“However, the water is being treated properly and then supplied for drinking purpose”, he informed the House.

Adding to this, Parrikar said though the manganese content is high in the intake water, it is reduced drastically through filtering process.

“The water supply gets affected since this filtration process takes more time than the normal time required for filtration”, he said.

Sardesai, during discussion, pointed out that NIO Director S W A Naqvi had discarded the theory of iron ore mines around Selaulim reservoir were the cause of it.

According to NIO report, said Sardesai, the sediments are rich in iron and manganese because of the composition of the source rock in the region.

Sardesai said his reliable information reveals that the reservoir was the location of an old manganese mining lease, which is now at the bottom of reservoir.

Opposition leader Pratapsing Rane said the manganese level could be high as the source of intake water was adjacent to Shantilal Khushaldas Gosalia’s mine.

The chief minister agreed to his suggestion to shift the intake source but said the process is not that easy.

He said the water scarcity problem of Mormugao taluka would be solved by April end once 30 MLD of water would be taken to Verna from Dovorlim, meeting the port town’s requirement of 70 MLD.

The Mormugao taluka presently gets only 45 MLD of drinking water.

Dhawalikar however said the whole problem would be resolved only when another treatment plant at Sanguem is commissioned by 2015.

When Dabolim MLA Mauvin Godinho started shouting at him why same answer is given to the House, Dhawalikar said it is delayed because the erstwhile Congress government was sitting on the proposal for seven years, from 2003 to 2010, without even issuing a tender.
